Why is this chapter titled “The Rice Sandwich?” Would another title be more appropriate?

In this chapter, Esperanza wants to eat in the school lunch room, the canteen, because she is under the impression that "the special kids" eat there. To her, not returning home for lunch seems to be an exciting prospect. After finally convincing her mother to let her take her rice sandwich to the canteen, Esperanza's illusions are shattered when a nun makes her point to her house from the window and tells her she lives too close and cannot eat there again.

You might retitle this chpater "Neighbors Not Welcome."
